Patricia is an exceptionally versatile PhD, with specialties in microbiology, HIV and Bioinformatics research. She is happy working diligently either as an individual or as part of a team; addressing and calmly resolving problems even under pressure. Her creative outlook drives continuous improvement through seeking innovative solutions, with a natural ability to refine processes and bring the best out of her team. Her proven ability to deliver work successfully is a result of a full commitment which builds trust and respect leading to project success. She brings enthusiasm and a positive attitude to any team environment, fostering a collaborative and transparent work ethic.


  • PhD in Molecular Biology (Cum Laude distinction), Universidad Autónoma de Madrid, January 2017
  • MSc Bioinformatics and Computational Biology, Escuela Nacional de Sanidad, Madrid, October 2014 - May 2015
  • MSc Microbiology and Parasitology, Universidad Complutense de Madrid, Madrid, Oct. 2011 - July 2012
  • BSc (Hons) Biology, Universidad Complutense de Madrid, Madrid, Oct. 2005 - Feb. 2011


During the last two years, Patricia has been working as a Bioinformatician at the University of Birmingham (cancer and genomic science) in Saponaro group. During this period, she analysed “omics data” and established pipelines for ChIP-seq, RNA-seq and Repli-seq in different samples, enhancing her confidence in carrying out genome wide analysis. As the only bioinformatician in the team, she gained wide experience solving problems, using her own initiative and working closely with her colleagues.

In January 2017, Patricia finished her PhD in HIV-1 Molecular Epidemiology and the implications of AIDS in perinatally infected children and adolescents  As part of her PhD project, she has analysed clinical, immunological and virological follow-up in perinatally HIV-1nfected children and adolescents from the Madrid Cohort.

Several projects have been accepted for publication by international scientific journals:

Patricia gained wide experience using human data, big databases and analysing the results obtained to improve clinical management of HIV-1 nfected children carrying triple resistance in Spain. A key inspiration has been the realisation that this work can contribute to develop future therapeutic options through different drug combinations.

As part of her PhD, Patricia has worked in Stanford University with Dr. Robert Shafer, analysing a high number of HIV-1 sequences and their factors to modulate the evolution of HIV infected patients.  During this period, she learnt an extensive amount of bioinformatics programming skills. 

Patricia is keen to continue her career in bioinformatics focussing predominantly on the analysis and management of clinical and epidemiological data.
